The latest
blow to the myth of vestigial organs comes from a recent study
on the leg of the horse. In an article in the 20-27 December
2001 issue of the journal Nature, titled "Biomechanics: Damper
for bad vibrations," it is noted that "Some muscle fibres
in the legs of horses seem to be evolutionary leftovers with
no function. But in fact they may act to damp damaging vibrations
generated in the leg as the horse runs." The article reads
as follows:
Horses and camels have muscles in their
legs with tendons more than 600 millimetres long connected
to muscle fibres less than 6 millimetres long. Such short
muscles can change length only by a few millimetres as the
animal moves, and seem unlikely to be of much use to large
mammals. The tendons function as passive springs, and it
has been assumed that the short muscle fibres are redundant,
the remnants of longer fibres that have lost their function
over the course of evolution. But Wilson and colleagues
argue… that these fibres might protect bones and tendons
from potentially damaging vibrations….
Their experiments show that short muscle
fibers can damp the damaging vibrations following the impact
of a foot on the ground. When the foot of a running animal
hits the ground, the impact sets the leg vibrating; the
frequency of the vibrations is relatively high-for example,
30-40 Hz in horses-so many cycles of vibration would occur
while the foot was on the ground if there were no damping.
The vibrations might
cause damage, because bone and tendon are susceptible to
fatigue failure. Fatigue in bones and tendons is the accumulation
of damage resulting from repeated application of stresses.
Bone fatigue is responsible for the stress fractures suffered
by both human athletes and racehorses, and tendon fatigue
may explain at least some cases of tendonitis. Wilson et
al. suggest that the very short muscle fibres protect both
bones and tendons from fatigue damage by damping out vibrations…316
In short, a closer loot at the anatomy of the
horse revealed that the structures that have been considered
as nonfunctional by evolutionists have very important functions.
In other words, scientific progress demonstrated
that what was considered to be evidence for evolution is in
fact evidence for design. Evolutionists should take a hint
from this fact, if they are willing to do so. The Nature
commentator seems to be reasonable:
Wilson et al. have found
an important role for a muscle that seemed to be the relic
of a structure that had lost its function in the course
of evolution. Their work makes us wonder whether other vestiges
(such as the human appendix) are as useless as they seem.317
This is not surprising. The
more we learn about nature, the more we see the evidence for
creation. As Michael Behe notes, "the conclusion of design
comes not from what we do not know, but from what we have
learned over the past 50 years."318 And
Darwinism turns out to be an argument from ignorance, or,
in other words, an "atheism of the gaps."
